Abstract

Η παρούσα εφεύρεση αναφέρεται σε μια υδρομεταλλουργική διεργασία για την ανάκτηση και διαχωρισμό πολύτιμων, βασικών ή σπάνιων στοιχείων όπως μέταλλα της ομάδας του λευκόχρυσου (PGM), του χρυσού και / ή του αργύρου, και άλλων πολύτιμων βάσεων και σπάνιων μετάλλων όπως νικέλιο, κοβάλτιο, χαλκός, ένα στοιχείο σπάνιων γαιών (REE) όπως το ύττριο και / ή το σκάνδιο, καθώς και το ουράνιο, το θόριο, το μαγγάνιο, ο ψευδάργυρος, το κάδμιο, το μολυβδαίνιο, το τιτάνιο, ο κασσίτερος και άλλα δευτερεύοντα στοιχεία όπως το βανάδιο, το γερμάνιο ή / και το γάλλιο από υλικό ζωοτροφών που περιλαμβάνει μεταλλεύματα, συμπυκνώματα και άλλα υλικά. Συγκεκριμένα, η διαδικασία περιλαμβάνει ποσοτική αφαίρεση πρόσθετης βάσης, σπάνια στοιχεία και ανθρακικά στοιχεία για αυξημένη αποτελεσματικότητα περαιτέρω επεξεργασίας των στερεών για ανάκτηση πολύτιμων μετάλλων ή / και ανακύκλωση και / ή διαχωρισμό πολύτιμων μετάλλων από υπόλειμμα απόπλυσης υπό πίεση και μπορεί να ενσωματωθούν σε μία ή περισσότερες υπάρχουσες διαδικασίες εκχύλισης πολύτιμων στοιχείων.The present invention relates to a hydrometallurgical process for the recovery and separation of precious, base or rare elements such as platinum group metals (PGM), gold and/or silver, and other precious base and rare metals such as nickel, cobalt, copper , a rare earth element (REE) such as yttrium and/or scandium, as well as uranium, thorium, manganese, zinc, cadmium, molybdenum, titanium, tin and other minor elements such as vanadium, germanium and/or gallium from feed material including ores, concentrates and other materials. In particular, the process includes quantitative removal of additional base, rare elements and carbonate elements for increased efficiency of further processing of the solids for recovery of precious metals and / or recycling and / or separation of precious metals from pressure washing residue and may be incorporated into one or more existing processes of extracting valuable elements.
